Assembling Your Microscope

Before you can view through your Celestron microscope, the binocular head assembly must be
attached to the pillar stand (13) and the rubber eyecups must be placed over the eyepieces. To
attach the binocular head assembly:

1. Remove the safety screw from the top of the pillar stand (13).

2. Partially unthread the pillar stand locking bolt (12) located behind the focuser assembly.

3. Place the binocular head assembly onto the pillar stand (13) and slide it half way down the
stand. Be careful not to put too much tension on the cord that goes from the microscope base
to the top light illuminator (10).

4. Rotate the binocular head assembly until the objective turret (5) is directly over the center of
the stage (7).

5. Tighten the pillar stand locking bolt (12) to hold the binocular head assembly in place.

6. Thread the safety screw back onto the top of the pillar stand.

To Attach the Rubber Eyecups:

1. Place the rubber eyecups over the eyepieces with the rubber lips facing up.

2. Push the eyecups down over the tops of the eyepieces.

3. Rotate the eyepieces so that the rubber lips are facing out to the sides.

Your microscope is now ready to view specimens.

Microscope Operation

Powering the illuminator:

Your Celestron microscope has a built-in, 3-setting illuminator powered by 110v AC power. To
power the illuminator:

1. Plug the power cord (8) into a wall outlet.

2. Turn the illuminator switch (9) to the "I" setting to turn on the bottom illuminator bulb.

3. Turn the illuminator switch (9) to the "II" setting to turn on the top illuminator bulb.

4. Turn the illuminator switch (9) to the "III" setting to turn on both the top and bottom
illuminator bulbs.

Viewing a Specimen

To view a specimen:

1. Place the round glass stage plate (7) into the opening above the illuminator. When viewing a
specimen using top lighting only, you may wish to replace the glass stage plate with the
black/white stage plate.

Specimens of different size and thickness will require different levels of illumination.

Tip:

Experiment with different lighting for each specimen. When using top lighting, the white side
of the stage plate may wash out fine detail where as the black side will increase contrast but
may make the specimen less bright.

2. Place a specimen slide under the specimen holder clips (6) and center the specimen directly
in the center of the stage.

Focusing:

To achieve the best focus with your microscope, not only can you make adjustments with the
focus adjustment knobs, but you can also adjust the left diopter ring as well as the interpupillary
distance between the eyepieces. To achieve sharpest focus:

1. Rotate the objective turret (5) to the 2x position . (Always begin by viewing a specimen at low
power, then switch to high power when needed).

2. Turn the focus adjustment knob (11) until the specimen comes into focus. If there is not
enough travel in the focuser mechanism to reach focus, it may be necessary to loosen the
pillar stand locking bolt (12) and slightly raise or lower the entire binocular head assembly
until the image becomes sharp.

3. Next, while looking through the eyepieces, adjust the interpupillary distance by sliding both
eyepieces side to side until the whole field of view can be observed through both eyes at the
same time.

4. Finally, close your right eye and turn the left eyepiece diopter ring until the image is in sharp
focus through the eyepiece.

If higher power is desired, rotate the objective turret (5) to the 4x position and readjust the focus
knobs (11) until the specimen comes into focus.
